Yes, I mistyped- the backend should auto detect the need for LUT on the ix1500 too. I'll note that your example command lines have weird emdashes before the contrast and brightness, not a proper double dash. Any chance that is related?
If not, can you get a debug log like so: SANE_DEBUG_FUJITSU=35 scanimage --mode=gray --contrast=20 --brightness=20 --format=tiff --ald=yes --device-name=fujitsu:ScanSnap\ iX1500:94839 --resolution=200 --batch=Scan-Designer-TAWS27-144246-%d.tif 2>ix1500.log then compress ix1500.log and send it to me directly? allan On Fri, Feb 14, 2020 at 4:53 PM Tom Buckler <t...@buckler.ca> wrote: > It's with the ix1500's not 500.
